>> I'm now deploying openstack 3 nodes (actually, I attached another compute, so my current deployment setup is 4nodes, i.e., 1 controller, 1 network, and 2 computes) by following the openstack installation guide, http://docs.openstack.org/kilo/install-guide/install/yum/content/neutron-controller-node.html <http://docs.openstack.org/kilo/install-guide/install/yum/content/neutron-controller-node.html>. I think several options in /etc/nova/nova.conf, /etc/neutron/plugins/ml2/ml2_conf.ini and /etc/neutron/neutron.conf should be modifed properly in order to use LinuxBridge instead of OVS.

>> 2. /etc/neutron/plugins/ml2/ml2_conf.ini on controller
>> Do I still need to modify this file? I'm confused, because the file name is 'ml2', which is for ml2 plugin not for 'linux bridge'... And, I wonder the lists should be modified.
